[PATCH v2 0/6] OLPC 1.75 Keyboard/Touchpad fixes

[Lubomir Rintel]

This makes keyboard/touchpad work on a DT MMP2 platform.

Changes since v1:
- Collected Acks
- Replaced "Input: olpc_apsp: depend on CONFIG_OF" patch with "Input:
  olpc_apsp: drop CONFIG_OLPC dependency", since it was correctly
  pointed out that the driver doesn't actually depend on OF.
- Dropped "Input: olpc_apsp: allocate the GPIOs used" and "dt-bindings:
  olpc,ap-sp: add GPIO lines" since at the moment they are not useful
  for much more than documenting the lines the SP uses and actually
  claiming them was deemed not to be a good idea.
- Fixed error handling in the "enable the SP clock" patch.

Cheers
Lubo
